HOT -WATER GEN ERATO R.

SPECIFICATION forming part of Letters Patent No. 239,724, dated-Apri1 5, 1881. Application filed July 26, 1.880. (No model.)

To` all whom ttmdg/ concern Be it known that l, J. D. CARMODY, a citizen ot the United States, residing at Evansville, in the county of Vanderburg and State ofIndiana, have invented certain new and useful Improvements in Hot-Water Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it app'ertains to make and use the same, reference being had to the accompanying drawings, and to letters or gures of reference marked thereon, which form a part of this specification.l 1

M vinvention relates to the device which Idenominate a sectional extension water-heater,77 adapted for use and service in greenhouses, laboratories, conservatories, baths, schoolhouses, residences, public buildings, and the like; and the novelty consists in 'the construction and arrangement of parts, aswill be moreA fully hereinafter set forth in the claims.

The vessel is made in sections, each section having a water-chamber, the only communication from which is the water inlet or outlet, or the adjacent section, as will be explained. These sections are of diiferent shapes internalf l but their outlines agree so that being seb 7 b cured together, they form a compact body. Each section has water com munication with its fellow or with the outside, and the sections are secured together by a rod and nut, said rod passing through the water apertures, but be ing of sufficiently smaller diameter to allow the free passage of' the water.

My Water-heater, being made in sections, as will be explained in reference to the drawings, allows each user to build his heater of a size to agree with the service required.

To enable others skilled in the art make and use my invention, I will describe its construction and operation, and to this end I refer to the accompanying drawings, in which- Figure lis a longitudinal vertical section in perspective. Fig. 2 is a view of the lire-box section in perspective. Fig. 3, one of the end sections in perspective. Fig. 4, one of the impacting or draft sections in perspective; and Fig. 5, a side elevation, showing the masonry and the several sections secured together by headed rod and nut, to form thecomplete heater.

Referring to the drawings, A represents the brick-work or masonry, and a the aperture for the ash-pit, governed by the draft-door a.

B represents the front-end section, having 5 5 feed-'aperture b, controlled by door b', nut- A bearing w, and aperture :r,`for the headed rod X and uut x2, as shown.

C represents the tire-box sections, having water-chambers C" and ports c.

D represents the impacting or draught sections, having apertures d d', and central aperture, d, as shown.

E represents the horizontal portion of the grate, and E the inclined portion. Between the inclined portion E ot' the grate and the lrst impacting-section is the draftspace e, as shown.

Havingthus described the construction with reference to the drawings, I will proceed to de- 7o scribe the operation and advantages.

The-section B, which forms the front or feed section, when reversed, with or without the door b, becomes the back or rear section. In either position the parts agree.

The sections C are so constructed as to make room for the lire-box; or, in other words, the sections C, in connection with the grate E, form the lire-box. Of course the length of the firebox will be governed by the number ot' sec- 8o tions G used and the purpose sought to be subserved.

The sections D are the absorbing and impactin g sections. As represented, the first one has the openings near the top and forms the back of the tire-box, against which the upper or inclined portions ofthe grate-bars rest. The succeeding sections D are reversed, so as to brin gthe ports below, thus impaetingthe flame, and torturing its course. 9o

The advantages of this construction must be obvious. The space e supplies oxygen to the fuel at the back of the grate E. The sections are so constructed that any purchaser may build a heater to suit the occasion. The bind- 9 5' ing-rods only affect the end sections, and do not obstruct the flow of water, although operating in the ports.

What I claim as new is- 1. The water-heater herein described,formed roo in sections, said sections being adapted to be secured together and to form a combustionchamber and an impacting chamber, the end sections being interchangeable with each other by being vertically reversed, and the impacting sections being reversible vertically and interchangeable at Will, as specified.

2. The sections B B', adapted to form the ends of a sectional Water-heater, and to be connected with the other or intermediate sections by rod and nut, and to be vertically reversed, as described, and to serve as set forth.

3. The sections D D, adapted to be reversed vertically, and arranged with the openings in one section near the top and-in the next section near the bottom of the furnace, and so on alternately, so as to give rst a rising and then a falling course to the products of combustion, as specified. A

4. The combination of the reversible end sections, B B, having seats as, and perforations x', with the intermediate sections, and the connecting-rods x2 X, as specified.

5. In a sectional boiler, the vertically-reversible and interchangeable sections D D, each having apertures d d d', constructed and adapted to serve as set forth, one of the sections D forming a bridge-Wall for the tire-box, f
